But, it is slower, and not quite as Arduino friendly. Be sure to check out the rest of the stuff on the ELM-ChaN site as well, tons of great info. FFT tutorial from alwayslearn.com: This site is great for breaking down how the fft works, into an easily understood format. highly...

N/2 bins. the fft size is limited by the 2kB SRAM in the arduino. the code is written with this is mind, and would need a few variables to be transferred from bytes to ints to make it work with larger ffts. 该fft在16b实数输入上运行,并返回8b线性, 16b线性或8b对数输出。它可以在任...
